gm COOLER.

Application filed April 26, 1924. Serial No. 709,320.

My invention is an improved aircooler and humidifier.

The object of my invention is to provide an apparatus to cool the air, which may be readily installed in a room, a food cooler, a car, etc. with a minimum amount of labor.

Another object is to provide an apparatus of this character, which is simple in construction, efficient in operation, vand inex- Figure 3 is a sectional view taken on the line 33 of Fig. 2.

Figure 4 is an enlarged fragmentary sectional view of the water receptacle.

Figure 5 is aplan view of the spacmg ring.

Referring more particularly to the drawing, a housing 1 is divided into two compartments 2 and 3 by a transverse wall 4. A blower 5 of any well known type is mounted upon the wall 4, and a hood 6 extends from an opening 7 in the rear wall of the compartment 3 to the intake of said blower. Adjustable shutters 8 are mounted in the opening 7. The blower 5 discharges through a central opening 9 in the wall 4 as will be fu ther described. An electric motor 10 drives the blower 5 and a centrifugal pump 11 is also driven by said motor, the purpose of which will be further described.

A water rece tacle 12 is secured to the I lower side of t e wall 4 into which the pump 11 discharges through a pipe 13. A central opening'14 is provided in the receptacle 12 through which the blower 5 discharges. A s irally formed depending flange 15 exten s from the bottom of the receptacle 12, and a plurality of holes 16, are formed in the bottom of said receptacle adjacent said flange. The water which flows through these holes is directed inwardl a ainst the flange by bafile lates 17. X fi rous material 18 1S suitaby secured to the lower edge of the flang'elfi and .wth an inlet openin and an outlet opening in the lower comextends downwardly adjacent the bottom of the compartment 2. The lower end of the material 18 is secured in a spiral form to a plate 19, similar to the manner in which it is secured to the recetpacle 12. It will be seen that as the water flows from the holes 16 upon the material 18 it will saturate said material, thereby humidifying the air passing thereover from the blower 5. Water is placed in the bottom ofthe compartment 2, to cover the lower part of the material 18, and the intake pipe 20, of the pump 11, extends into the water. Thus the pump 11 carries the water from the compartment 2 into the receptacle 12, where it passes through the openings 16 upon the material 18, and drips back into the compartment.

To compensate for the expansion and contraction of the material 18, the plate 19 is yieldably secured to the bottom of the compartment 2, by a plurality of springs 21, secured to said plate and to the bottom of said compartment.

The air from the blower 5 passes downwardly through the openin 14 in the recep ring 24 is provided which is secured to the fibrous material 18 midway between plates 12 and 19 and spaces the first spiral turn so that the air may enter.

It is readily understood that a disinfectant -or perfume maybe placed in the compartment 2, and thus carried into the room y the air passing therethrough.

Having described my invention I claim ,1. A cooler and a humidifier comprising a cylindrical housing, a transverse wall in said housing dividingthe same into an upper and lower compartment, a blower, an electric motor, and a centrifugal pump mounted on a common shaft in the upper compartment, said housing being rovided adjacent sai blower partment, a water receptacle secured to said wall having an opening therein through which air is downwardly forced, a fibrous curtain secured to said receptacle, said receptacle having openings therein adjacent said curtain, a plate to which the lower end of said curtain is secured,a spacing ring positioned intermediate of said plate and said water receptacle and springs secured to said plate and to thefloor of said housing.

2. A cooler and humidifier comprising a housing, an inlet opening and an outlet opening in said housing, adjustable shutters in said outlet opening todeflect the outgoing air, a blower located adjacent said I inlet opening, a'water receptacle within said housing having an opening therein for the passage of air, a fibrous curtain secured to said receptacle in such a manner as to provide a spiral air passage, said receptacle being perforated to permit passage of water therefrom onto said curtain, an electric motor and a centrifugal pump mounted on a common shaft with said blower, a feed pipe from the lower portion of said housing to said pump, a plate to which the lower end of said curtain is secured, and tension springs detachably secured to said plate and to the floor of said housing to maintain said curtain in a taut condition.

In testimony whereof I aflix my signature.

EDMOND R. COOK.
